To all whom it may concern.-

Be it known that I,".I AMES M. DODGE, a citizen of theUnited States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Chutes for Loading Vessels,

Cars, dac., of which the following is a specification.

The object of my invention is to provide an ordinary chute for loading vessels and cars with coal or other material with a section which can be drawn into the trough, or lowered so as to hang therefrom in order that coal as it is delivered will not fall a great dis` tance but will 110W into the vessel or other receptacle without causing a great percentage of breakage.

Referring to the accompanying drawings:- Figure 1, is a View showing my invention applied to a coal chute mounted on a dock, with a vessel in section. Fig. 2, isa View of a portion of Fig. 1, showing the position of the telescopic section elevated to accommodate the increased height of the body of coal. Fig. 3, is an enlarged sectional -view of the coal chute showing the telescopic section partly within the chute. Fig. 4, is a plan View of Fig. 3. Figs. 5, 6 and 7, are detailed views Aof the telescopic section. Fig. 8, is a view showing the valved end sections.

3o Referring in the first instance to Figs. 1 and 2, A is the trestle work supporting the coal bin A into which coal is dumped from the cars on the tracks above and extending from this bin is a tixed chute B to whichis hung at b the vpivoted chute B', this vchute can be raised or lowered by the chain h extending from the outer portion of the chute Ato a drum b2,by this means the pivoted chute can be raised to the position shown by dotted lines in Fig. 1, or lowered to the position shown by full lines in said Iigure, or any intermediate position.

The ychute in' the present instance has a curved outer end c, provided with a cover c', and on each sideof the chute is a rail c2 on which travel the wheels or rollers d of the telescopic section D when in the chute, as clearly shown in Fig. 3.

The telescopic section D is made up of a l5o number of pivoted parts D', the end of one part itting into the end of the adjoining part,

Serial No. 510,602. (No model.)

as shown in Figs. 6 and 7, the parts are so shaped that they will move freely, yet will he sufcientlytight to prevent small particles ofV coal clogging the joints, andthe parts 5 5 are so arranged that the forward en'd of one part will fit into the rear end of the adjoining part, so that'as' vthe coal Iiows through the chut-e its flow will not be impeded by any projecting ends.

In order to provide an even surface for-the passage of coal I expand the rear portion d of each section D', so that the coal will low over a practically even surface. In the present instance each section D is made quadrangular in cross section as shown in Fig. 5, and extends across the chute B; the bottom of the rst section is arranged to come in contact with the bottom of the chute so that as the coal flows through the chute, it will flow 7o into the first part of the telescopic section and will then Iiow through the entire length, and discharge into the Vessel or other receptacle, as shown in Fig. 1.

E are the chain links on which are mounted the rollers or wheels d, the pivot pins e of these links pass through one end of each section so as to secure the sections D together and the outer links are L-shaped and act as braces being secured' tor the sections at e', 8o Fig. 7.

The end links are secured to chains or ropes t', at each side of the chute, and these chains or ropes pass over a sheave t to a drum 'i2 driven by the ordinary winding mechanism either by hand or by power, so that by simply turning the drum, the telescopic section D can be drawn into the chute.

The telescopic section can be entirely drawn into the chute and is confined therein by the 9o guard rails c3 on the upper 'edge of the chute Y (Figs. 3 and 4), so that when the lchute is elevated to the position shown by dotted lines in Fig. 1, the telescopic sections will not be dislodged.

The operation is as follows:-It`, for instance, a vessel is to be loaded with coal, the chute is moved to the position shown by full lines in Fig. 1, and the telescopic section is .lowered until it assumes the position shown rooy in said ligure, coal is allowed to low through the chute into the vessel, and as the pile of coal increases, the telescopic section is raised and drawn into the chute, until it assumes a position, forinstance, as shown in Fig. 2, with a very small portion of the chute exposed. When the telescopic section is within the chute, it is entirely out of the way and protected and the chute can be used either with, or Without, extending the section. The lower end of the telescopic section may be provided with doors or gates, as shown in Fig. 8, or the ilow of coal may be regulated by the chute itself.

I claim as my invention- 1. The combination of a chute, with amovable extension consisting of a series of piv oted sections adapted to be drawn into the chute, substantially as described.

2. The combination of a pivoted coal chute,

with a exible telescopic section adapted to the chute, substantially as described.

8. The combination of a chute, an extension adapted to be drawn into the chute and having sections linked together with rollers adapted to travel on the chute and mechanism for drawing the extension into the chute, substantially as described.

4. The combination of a chute, a telescopic extension consisting of a series of quadrangular sections, links extending from one section to another, rollers adapted to travel upon the chute and means for operating the telescopic section, substantially as described.

5. The combination of the pivoted chute having a curved end, the telescopic extension adapted to said chute consisting of a series of quadrangular sections, a link secured to one end of each section, and rollers carried by the links, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
